EMBROIDERING ATTACHMENT FOR SEWING MACHINES.

Application ined April 1o, 1920. Serial No. 379,759.

T10 @ZZ whom 'it may concern Be it known that I, MARTIN HEMLEB, va citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements'in Embroidering Attachments for Sewing Machines, of which the following 1s a specification, reference beinghad therein to the accompanying' draw-- ings.

-This invention relates to attachments for sewing machines and particularly to that class of attachments whereby a straightaway stitching machine may be easily converted into an einbroidering machine.

This has heretofore beenaccomplished by rendering the feeding mechanism ineffective land manually shifting the work between successivey stitches.

this cla-ss ofwork'vwhicli'uis simple and inexpensive in construction, effecti've in operation and which may be easily substituted for the usual presser-foot used for Straightaway stitching.

The invention preferably comprises a needle-stripper having a shank slidingly held in a guide-way formed in the needleclamp of the machine and a laterally projecting foot portion provided with a needle aperture. A spring acts uponthe needlestripper to yieldingly hold it depressed with i' respect to the needle-clamp.

The improved form of needle-stripper may be employed advantageously in connection with the feed cover-platev disclosed in U. s. Patent No. 997,119, dated Oct. 19, 1909 to Chas. Stafford and is so illustrated in the accompanying drawings in which Fig. l1 is a perspective view of the attachment applied to the needle-bar ofl a Sewing machine, together with the feed cover-plate above rer ferred to. Fig 2 is a central vertical sectional View of the parts shown in Fig. 1. Fig. 3 is a Side elevation thereof with the When machines are so operated it is dethroat-plate and feed cover-plate -in section and with the needle-bar inits lowermost po- 1 sition and the needle-stripper lifted-byk its Contact with the fabric. Fig. f1 a rear side elevation of the improved needle-stripper and Fig. 5 is a Sectional view ytaken on the line 5-5 of Fig. 3.

Referringr more particularly tothe drawf ings the improved needle-stripper is shown sustained by the needle-bar 1 provided with a groove 2 for Vthe reception of the needle 3 which cooperates with a suitable loop-taker (not shown) locatedbeneath the throat plate 4 which is provided with feed slots '5 and a needle-hole 6. A feed cover-plate 7 is supported by the throat-plate el and acts to render ineffectivea suitable feed-dog (not shown) which normally operates through the feed slots 5. A needle-clamp 8, in the form of a sleeve, is fitted about the lower end of the needle-bar and is formed withl a boss 9 through which is threaded a clamp screw 10 having its`inner' end vcontacting with the needle-bar 1 4thereby securing the needle clamp to the needle-bar land the needle 3 in the' groover 2; l l *i The improved needle-stripper comprises preferably a shank portion l1 and a later-` allyV projecting footportion 12 provided `with aneedle aperture This shank 11 is slidingly mounted in a 'guide-way'll formed" in guide-block 141 fixedly secured to the needle-clamp 8, and is provided with an aperture 15 affording clearance for the boss 9 which projects through the Shank 11 and guideway 14. A spring 16 acts to yieldingly hold the'rieedle-stripper depressed with respect to the needle-clamp and is provided with one arm 17, which is connected to the guide-block 14 and another' arm 18 connected lat 19 to the shank 11. f

vInasmuch as the needle-stripper isslidinglyk Secured to the needle-clamping sleeve independently of the clamp-screw, it is obviousvthat the screw may be loosened for the purpose of replacing the needle without disturbing the operative relation between the clamping sleeve and the needle-stripper.

stitch the needle-stripperdescends in unison tactsl with thekfabric f, then a continued downward movement of the needle-bar corn- Vpresses the spring 16 and slides the shank upwardly in the guideway 14 until the During the formation of an embroidery lwith the needle until the foot-portion conneedle-bar reaches the limit of its downward movement as shown in Fig. 3. -From this position the needle moves upwardly and throws out the thread-loop which is seized by the loop-taker. During the initial upward movement of the needle the oot l2 bears upon the fabric under the action of the spring 16 and prevents the fabric from clinging to and rising with the needle and thus preventing complete formation of the loop. After the needle thread-loop has been seized bythe loop-taker the boss 9 comes in contact with the upper wall of the aperture and causes the foot to rise thereafter in unison with the needle.

f Having thus set forth the nature of the invention what I claim herein is:

l. An embroidering attachment including, in combination, a. Y needle-clamp provided witha, lateral boss, a guide-block secured to said needle-clampand formed with a guideway, a needle-stripperr provided with a f slotted shank entered by the. needle-clamp boss and slidlnglvmounted in` saidy guidestripper slidingly mounted thereon and sup.

ported solely bv said needle-clamping sleeve, a springy for said needle-stripper, and means carried by sa1d sleeve,l for securingr it to said needle-bar and for causing said sleeve t clamp; said needle in said groove.

3. In, an embroidering attachment for sewing machines provided with a needle-bar having a groove for the reception of a needle,

in combination, a needle-clamp secured to said needle-bar, a guide-block supported by said needle-clamp, and formed with a guideway, a needle-stripper slidingly mounted in said guide-way, a spring having an arm con nected to said guide-block and anothervarm connected to said needle-stripper for holding the latter depressed 'n said guide-way and a clampfscrew threaded through said needle.- clamp and contacting with the needle-bar for securing said needle-clamp and needlestripper tothe needle-bar and for causing said sleeve to clamp a needle in the groove in said needle bar.

4. In an embroidering attachment for sewing machines having a needle-bar provided with an external groove for receiving a needle, in combination, a needle-clamping.

sleevei surrounding said needle-bar. a clamp,-,

screw threaded through said needle-clamp .ing sleeve and contacting with said needlebar for securing said needle-clamping sleeve to said needle-bar and causing said sleeve to clamp a needle insaid groove, and a springpressed needle-stripper slidingly mounted' on said needle-clamping sleeve and supported solely thereby and independently of said clamp-screw. n

5. An embroidering attachment including in combination, a needle-clamp having a lateral b0ss,` a guide-block secured to said clamp and formed with a guideway. a needle stripper slidingly mounted in said guideway in engagement with said boss b v which it is maintained in the guidewav, and a spring for yieldingly holding said stripper depressed relatively to the needle-clamp.

In testimony whereof, I have signed my name to this specification.
